Application .filed March 16, 1925. `Serial No. 15,893.

f structed that it is of attractive and pleasing appearance, and which may be most readily adjusted to throw the light upon the picture, for example, in any desired direction, and which also may be adjusted vertically or laterally with respect to the picture to secure the best results.

In devices of this type it has been frequently the case that the lamp socket loosened during use and particularly dueI to the adjustment of the reiiecting hood or shell which gradually unscrewed the socket as the shell was rocked back and forth. Further diliiculty has been experienced due to the loosening' of the vertical and lateral adjustments as they are usually dependent solely upon the frictional yengagement of a single screw.

This invention is designed to overcome such defects as those noted above, `and further objects of the invention are, therefore,

to provide a lamp protector in which the hood or shell may be freely rocked to secure the exact adjustment desired without any possibility of loosening of the lamp socket, and to provide vertical and lateral adjustments which are not dependent merely upon frictional engagement of a screw but are so formed that a very secure, firm, and reliable binding action is attained.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a view showing the reflector in position and with the major portion of the parts in section.

Figure 2 is a fragmentary plan view of the structure shown in Figure 1 such View being partly in section.

Figure 13 is a View from the rear side of Athe reetaf ,Shows-.1a a par@ af the reflector in section together with a part of the supporting arm.

Figure l is a sectional View on the line ofFigure 1. f

v Figure 5 is is a sectional view to an enlarged scale on the line 5,-5 yof Figure 1.

The reflector is supported by means of a bracket 1 secured to the picture frame 2 or to a suitablesupportand preferably upon the rear side of such support. This bracket is shown in greater detail in Figure 5 from which it will be seen` that` it is attached by means of screws Spassing through apertured ears extending laterally from the bracket. This bracket is provided with a rectangular groove or socket on its innervside which houses the square or rectangular hea-d l of a bolt 5, such bolt projecting through a bracket and outwardly therefrom. The rear side of the bracket is provided with a channel Shaving tapered walls for receiving the similarly beveled vertical adjusting and supporting bar 7 This bar is provided with plurality of elongated apertures 8 through which the bolt 5 passes. A wing nut 9 is used to clamp the bar into wedging engagement with the tapered guideway in the bracket 1, as most clearly shown in Figure 5, and to thus firmly lock the bar in any one of a multitude of adjusted positions, such locking being secured not solely by the binding action 'of a single screw, but by the cooperative wedging or binding action of the bracket and bari.

\ It is to be noted from Figures 1, 2 and a that the upper end of the bar is provided with a transverse rectangular slot 10. This slot 10, it will be noted particularly from Figure 2, is provided with inwardly directed ears 11 which extend' approximately half way up the slot. A lock screw 11 is threaded through the upper end of the bar for a purpose hereinafter to appear.

The laterally or outwardly projecting arm 12 is of rectangular cross section and is adapted to slide back and forth through the rectangular aperture in the bar 7. It is provided with a plurality of notches 13 contoured to fit the ears 11 of the bar 7, as shown in Figure 2, when the arm 12 is pressed downwardly into the lower portion of the slot 10 by ,means of the screw 11. i The outer end of the bar 12 is downwardly @B11-"ved, as. .indicated le Figure 1- At` SUO the upturned-portion 16 of a strap 16 andthus securely hold the strap against rocking motion. v through the outer end and through the strap A bolt ori.scretv., 17 isi passed.l

which may be locked inl a very secure and firm manner Without danger of subsequent loosening.

It vvilli'urther be seen that :tn-extremely 50 simple and practical form of adjusting hood and .support 4,therefor-,ist provided and that this hood vmay be mosteasily turned to secure 16 and carries a nut 18 on its inner end:l 1 Iti ,the eeactilighting desired.

is to be noted from Figure 1 that the nut is held between the ears'dls.andristhus pre vented from turning.

The bar 16 constitutes iny effect a supporting,yokle for the reflector, as mostcle'aijly'-v shoivn in Figures Qan-di; It is tobenotedt that the outer ends of theibar..y 1,6" are freceived in suitable'Y channelsdormediin heads Y 19, I These'headsgarepreiferably ornainentelgl', y
